Reasons Why An Ammeter Has Low Resistance. the working principle of an ammeter is that it must have very low resistance and inductive reactance. as shunt resistors used for ammeters have resistive values which are very low, usually they have to be made from relatively large. This low impedance is essential to minimize. an ammeter is designed to have a very low resistance inside it. in order to accurately measure the current without significantly altering it, an ammeter must have a very low resistance. Using ohm’s law where i = v/r is obvious that we need the resistance to be as low as possible. the resistance of an ideal ammeter should be zero. i understand why voltmeters are connected in parallel and ammeters are connected in series, but why is it that to measure voltage, you must have high resistance, and to. This is because an ammeter is connected in series in a circuit. in order to measure the current through some element of a circuit, the ammeter is placed, of course, in series with the element.
